The advantages of cold drawn steel tube:

(1) the size is accuracy, tolerance is small;

(2) when the die hole machining is excellent, well-oiled and the surface of good quality and finish of up to seven;

(3) using it to produce small-diameter steel pipe and a special section;

(4) cold contribute to grain refinement of metals, together with the appropriate heat treatment to obtain good mechanical properties of steel pipe;

(5) The equipment is simple, flexible production methods, and to facilitate the replacement of species.

In addition, forming speed high yield without damage coating made various section forms meet the use conditions; cold rolled Steel great plastic deformation improve steel yield points.
